Logistics Execution covers the areas of Warehouse Management and Inbound Receiving and Outbound Shipping processing.
Warehouse Management provides an additional level of stock location detail than SAP Inventory Management. Inventory Management only maintains stock quantities at the Storage Location level, which is typically an area of your warehouse or a building on your company’s campus. Warehouse Management manages stock down to the bin level, or to the physical coordinates within your warehouse. Warehouse Management also provides Picking and Putaway Strategy functionality.
